| 摘 要： | 针对卫星导航抗干扰需求，研究了基于自适应波束形成的多波束抗干扰技术. 为了解决传统固定多波束抗干扰方法在波束数目受限时无法兼顾所有导航卫星信号导致接收性能下降的问题，提出了一种基于K-means聚类算法的动态指向多波束抗干扰方法. 建立天线阵列进行仿真，结果表明，该方法在接收的北斗卫星信号数目多于波束数目时，抗干扰性能优于传统方法.

| Abstract: | In response to the anti-jamming requirements of satellite navigation, multi-beam anti-jamming technology based on adaptive beam forming is studied. In order to solve the problem that the traditional fixed multi-beam anti-jamming method cannot consider all the navigation satellite signals to reduce the receiving performance when the number of beams is limited, a dynamic multi-beam anti-jamming method based on the K-means clustering algorithm is proposed. The antenna array is established for simulation, and the results show that the anti-jamming performance of this method is better than the traditional method when the number of Beidou satellite signals received is more than the number of beams. |
